git/Q/Is it possible to have a submodule pointing to another commit

• Is it possible to have a git/submodule which points to a different commit of the same git repo?

  • Use case: langgraph/Platform allows deploying more than one AI graph at once, as long as there are separately addressable python applications. If it was possible to have a submodule in a <ai-app-name>-prod folder which pointed to a specific commit, then two versions of the same application could be accessed in one langgraph/Platform/Deployment.

  • Answer - Not possible with a single repo; must use two repos

    • It's possible to accomplish this with two repos:
      • ai-app-impl
        • v1 tag
        • v2 tag
      • ai-app - this is a single deployment
        • ai-app-prod/ (graph_id ai-app-prod)
          • git submodule that points to ai-app-impl@v1
        • ai-app-stage/ (graph_id ai-app-stage)
          • git submodule that points to ai-app-impl@v2
